So that's what an OHM is
Since: Dec 27, 2004
On a positive note, the mix sounds clean, the drums are clear, and the vocals are pretty upfront for you.
The kick drum, on my system, is really "thumping" which leads me to believe that most of it rests below 150 hz. I can make it out just fine, but on systems with lesser sub power the kick drum could be lost. You might want to give it some boost on the high end, beyond 2khz to lend it some snap and attack.
The guitar sound is very thin. I can still make out its articulation, but it's very weak; almost barely there. It sounds as if it only sits around the 1khz-3khz region, and not much else. You could give it more body around 350hz-1000hz, but it sounds like a recording problem. Is it digital, out of an amp, how was it mic'ed? etc.
The mix also lacks "width" and sits right dead-center. You could probably try hard panning on guitars for a "wall" of guitar sound, or just to spread them out. Maybe some panning on the vocal tracks to do the same. I'm not sure how you're recording the drums, but two right and left overheads can help give it a more "open" feel.
Overall though it sounds good and clean. Keep it up.
